He’s dead

Did you miss the part where he chose to die rather than live in shackles?

I mean if he goes to Wakanda to claim his throne after Infinity War, the battle in Black Panther won't even occur. He just needed to wait for few months. Very bad lucky.

No @Bund meant what if Killmonger decides to kill Klaue and bring him into Wakanda after the events of Avengers: Infiniy War. Then he can easily be the king. Because T' Challa has already vanished into ashes.

Killmonger had bad timing

M'baku is against this!
